Vitamin C vs Niacinamide: Which Serum Rules in 2025?


✨ Two Power Ingredients, One Skincare Dilemma

If you’ve been scrolling through skincare reels lately, you’ve probably seen two ingredients dominating every skincare shelf Vitamin C and Niacinamide. Both promise radiant, glowing, and youthful skin, but which one truly deserves a spot in your 2025 skincare routine?

At Cathy Doll India, we’re all about smart skincare. Let’s decode the benefits of these glow-boosting superstars and help you pick the right serum for your skin goals.

Vitamin C The Brightening Superstar

What It Does

Vitamin C is a powerhouse antioxidant that helps brighten dull skin, fade dark spots, and protect against environmental damage. It boosts collagen production and gives your skin that fresh, lit-from-within glow.

  • Even out skin tone for a naturally radiant finish

  • Protect your skin from UV and pollution damage

  • Keep your skin hydrated and smooth

💬 Perfect for: Dull, uneven, or tired-looking skin that needs instant brightness.

Pro Tip: Use in the morning after cleansing and before applying sunscreen for a radiant daytime glow.

Niacinamide The Barrier-Strengthening Multitasker

What It Does

Niacinamide (Vitamin B3) is the ingredient of the moment for calm, balanced, and blemish-free skin. It helps reduce redness, shrink pores, and strengthen your skin barrier.

Cathy Doll Niacinamide Serum The Balancing Hero

The Cathy Doll Niacinamide Serum is formulated to:

  • Minimize pores and excess oil

  • Fade acne scars and dark spots

  • Control sebum and prevent breakouts

  • Strengthen the skin barrier for smoother, clearer skin
